Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its protected amine and nitrile functional groups allow for selective transformations, making it valuable in multi-step organic syntheses. Commonly employed in the development of nootropic drugs and antiviral agents, where the pyrrolidine scaffold plays a key structural role. The Boc-protected derivative ensures stability during reactions and facilitates purification in solid-phase and solution-phase peptide-like synthesis.
